I have a g4 digital audio 733mhz with 1gb of ram and 17"apple studio display at highest resolution. I am very very happpy with this machine. There is just one thing... Graphics, it runs the Gforce 2 MX with the ADC port. When I am in certain websites, it gets a little choppy when scrolling, iphoto is choppy when scrolling through pictures and loading pictures into full view, opening up pictures in viewer (3.3mp pictures) has quite a delay when opening, zooming in an out of PDF's in viewer is extremely slow.. Im thinking it might just be video card. What could i do to make it run better in those areas? What video card would you recommend ( has to have ADC ). Another thing, I just installed an m-audio revolutions 5.1 card and installed all software and it works great, DTS in movies and all... but sometimes when a sound playback is started I get kind-of a static POP sound... lets say.. I was playing a song in iTunes then I pause it, then I go to quicktime and start a playback, it will sometimes make a static pop or maybe a tick sound... also, is there an alternative program to enhance my audio? M-audio's software has an option for SRS II surround sound emulation but I dont like it too much, it sounds too fake. Im using logitech Z680 5.1 speakers... any help or suggestions appreciated.
